DETAILED DESCRIPTION OF INVENTION:

The ‘GTank-C90 Auxiliary Fuel Transfer System’ consists of an auxiliary fuel cell sized and shaped to match the motorcycle frame utilizing these added/revised fuel lines, vent lines, fuel fill lines, fuel transfer lines, connectors, couplers, electric fuel pump, toggle switch, electronic timer, relay, wiring, fuse and connectors as noted. Fuel Lines Revisions:(consist of 7 lines):

The added/revised fuel, vent & fill lines for the ‘GTank-C90 Auxiliary Fuel Transfer System’ are as follows:

-   Line 1: Routes from the dual-end side of the first ‘Y’ connector to     the single-end side of the second ‘Y’ connector. -   Line 2: Routes from the dual-end side of the second ‘Y’ connector to     the out-flow side of the check valve. -   Line 3: Routes from the in-flow side of the check valve to the vent     stub-out of the fuel cell. -   Line 4: Routes from the dual-end side of the second ‘Y’ connector to     the fuel out-flow side of the electronic fuel pump. -   Line 5: Routes from the in-flow side of the electronic fuel pump to     the out-flow side of the fuel filter. -   Line 6: Routes from the in-flow side of the fuel filter to the fuel     transfer stub-out of the fuel cell. -   Line 7: Routes from the ‘L’ connector tapped into the stock rubber     filler hose to the fuel fill line stub of the fuel cell.

Connectors (3ea):

The connectors are fuel resistant, preferably nylon, material allowing for revisions and additions to the existing fuel system and hoses as follows: The ‘L’ connector ties into the ‘GTank-C90 Auxiliary Fuel Transfer System’ fuel fill line at the stock filler hose allowing for simultaneous filling of the auxiliary fuel cell and the stock fuel tank, eliminating the need for separate filling locations.

Location:

The ‘L’ connector is tapped into the existing stock filler hose allowing for simultaneous filling of both the auxiliary fuel cell and the stock fuel tank. The existing vent line is intersected by the first ‘Y’ connector allowing the single ended side of the ‘Y’ connector and one of the dual ended sides to connect to the new ends of the existing vent line. The second ‘Y’ connector divides the new vent line allowing for both venting and fuel transfer uses. The check valve is placed in the new vent line between the second ‘Y’ and the auxiliary fuel cell to eliminate fuel re-circulation during the fuel transfer process. The fuel filter is placed in-line on the inlet side of the electronic fuel pump to protect the pump from contaminants.

Fuel Pump:

The Fuel Pump is an automotive style electrically operated fuel pump, which transfers fuel from the auxiliary fuel cell to the stock fuel tank when activated. The Fuel Pump is located in a convenient location near the auxiliary fuel cell secured in place as necessary.

Electrical Components: Timer Circuit:

The electronic timer is a 12V electrically controlled adjustable component designed to control power to the fuel pump for a pre-set period of time allowing for safe operation. The electronic timer eliminates the need for manual shut down of the fuel pump during motorcycle operation. This is a safety feature freeing the operator from needing to shut off the fuel pump.

Emergency Shut Off Circuit:

The relay circuit is connected to the electronic timer circuit enabling the operator to shut down the timer circuit and electronic fuel pump at any time by activating the toggle switch in the opposite direction of circuit activation engaging the relay which disconnects the electrical power to the electronic fuel pump, shutting down the fuel transfer operation.

Fuel Toggle Switch:

Toggle Switch is a SPDT Switch; single pole double throw with momentary (on) in both its ‘up’ and ‘down’ positions, off is the center position. The ‘up’ position activates the fuel transfer process while the ‘down’ position activates the relay shutting down the transfer process at any time. The toggle switch has connectors allowing for electrical wires connections to the ‘GTank-C90 Auxiliary Fuel Transfer System’. The Switch is self centering leaving it in the ‘off’ position at all times.

Fuse Holder:

The fuse holder is an in-line 5amp fuse holder with small blade 5amp fuse. The purpose of which is to protect the fuel pump from power surges or shorts. This in-line Fuse Holder is located in the power wiring circuit just prior to the Fuel Pump.

OPERATION:

The operator fills the ‘GTank-C90 Auxiliary Fuel Transfer System’ simultaneously and in the same fuel filler location as the stock fuel tank. The filling process is complete when fuel remains visible in the stock filler neck and no longer drains down into either the stock tank or auxiliary fuel cell.

The stored fuel of the ‘GTank-C90 Auxiliary Fuel Transfer System’ is held in reserve in the auxiliary fuel cell until the fuel in the stock fuel tank has reached a capacity of less than 1/4 tank at which time the toggle switch can be activated, starting the fuel pump and associated timer circuit commencing the transfer of fuel from the auxiliary fuel cell to the tock fuel tank allowing for uninterrupted operation of the ‘motorcycle’.

During the operation of the motorcycle fuel is being drawn from the stock fuel tank as per its original design parameters by the original manufacturer, this process is not affected by the installation and utilization of the ‘GTank-C90 Auxiliary Fuel transfer System’. When fuel the level of the stock fuel tank reaches less than 1/4 capacity the operator turns ‘on’ the fuel toggle switch activating the electronic fuel pump thus activating the ‘GTank-C90 Auxiliary Fuel transfer System’. Upon activation fuel is drawn from the auxiliary fuel cell through the fuel filter via the electronic fuel pump through the second ‘Y’ connector through the first ‘Y’ connector and into the stock fuel tank via the existing vent line. The check valve at the new vent line keeps this fuel from re-circulating into the auxiliary fuel cell. The electronic timer shuts off power to the electronic fuel pump at a predetermined time correlating to the completed fuel transfer from the auxiliary fuel cell to the stock fuel tank.

The stock fuel tank, which is the direct supply source for the motorcycle operation, is now refilled and operation of the motorcycle proceeds. The fuel transfer process is designed to operate during normal motorcycle usage without disruption of the same.
